INTRODUCTION Nocturnal enuresis (NE) and obstructive sleep apnoea-hypopnoea syndrome (OSAHS) are common problems during childhood, and population studies have reported a significant correlation between them. This study aimed to assess whether habitual snoring, mouth breathing and daytime sleepiness are associated with increased incidence of NE in children with OSAHS. MATERIAL AND METHODS Poly...

BACKGROUND Among the indices able to replace invasive central venous pressure (CVP) measurement for patients with acute decompensated heart failure (ADHF) the diameters of the inferior vena cava (IVC) and their respiratory fluctuations, so-called IVC collapsibility index (IVCCI), measured by echocardiography, have recently gained ground as a quite reliable proxy of CVP. OBJECTIVES The aims of...

data envelopment analysis (dea) is a nonparametric technique that includes models to evaluate the relative efficiency of decision making units (dmus). it has the ability to separate efficient units and inefficient units. one of the applications of this mathematical technique is evaluating performance of supply chain. according to such as the inefficiency factors of one dmu, is existence congest...

BACKGROUND Clinical experience suggests that atrial tachyarrhythmias (ATs) are a frequent comorbidity in heart failure patients with left ventricular systolic dysfunction and that volume overload may increase AT susceptibility. However, substantiating this apparent relationship in free-living patients is difficult. Recently, certain implantable cardioverter-defibrillators provide, by measuring ...

For several decades growth of traffic volumes has outstripped investments in road infrastructure. The result has been a relentless increase in traffic congestion. This paper reviews the economic principles behind congestion pricing in static and dynamic settings, which derive from the benefits of charging travellers for the externalities they create. Special attention is paid to various complic...

This paper describes the use of Congestion Pricing as a means of providing Congestion Control and Di erentiated Quality of Service. The application of the proposed technique to the Internet Protocol has the advantage that it can be simply implemented using Explicit Congestion Noti cation. In particular: the network mechanism is independent of higher level protocols; the end systems can continue...

PURPOSE The aim of this study was to identify factors predisposing to lung infarction in patients with pulmonary embolism (PE). MATERIALS AND METHODS We performed a retrospective analysis on 154 patients with the final diagnosis of PE being examined between January 2009 and December 2012 by means of a Toshiba Aquilion 64 CT scanner. The severity of clinical symptoms was defined by means of a ...

INTRODUCTION Multiple studies found a significant correlation between B-type natriuretic peptide (BNP) level and clinical severity of heart failure (HF). We aim to study the ability of a single BNP measurement to predict the degree of congestion in acute systolic HF. METHODS Patients enrolled in the ESCAPE trial who were admitted with acute systolic HF were divided into tertiles according to ...
